Application of color sorter in wheat milling

The color sorting machines inspect grains by means of digital cameras and remove contaminants by a short burst of compressed air by using the colour difference. This machine has been successfully used in the rice milling industry for long time. Recently color sorters have begun to find their way into durum semolina milling and also into wheat flour mills.The color sorter are used in the wheat cleaning to remove ergot wheat, black tip, fusarium, burnt, other discolored grains and other inner contaminants. Today’s advanced color sorters are robust, compact, requires less maintenance and consumes very little energy. The color sorting has come of age and should be considered for inclusion in any modern wheat cleaning plant. Optical sorters are taking the place of traditional disc and indented separators in the wheat milling process. In the present review the use and integration of color sorter in wheat cleaning flow sheet were discussed in details.
